Don't Do Drugs

They say, and I suppose some of us have even seen it, that when you do just a lil too much Drugs and/or alcohol, a person does things that he would not do, when in his right mind. That leads to the conclusion, that if you are not in charge of what you are doing; then who in the heck is?
Lemmee tell you a story;
Many years ago, before I became a Christian, I went to an outdoor Rock concert. As was the usual, it was a two-day event. I went with my younger brother and his girlfriend.
We arrived IIRC on a Friday evening and set up our tents, then got into the alcohol. I was only about 20, and my brother just old enough to drive. By this time in life, I had learned that I could not handle the hard stuff, so I had just brought a lil beer. I mean we were on motorcycles so there is not much room.
Now comes the "funny" part.
I woke up on Sunday afternoon, two nights and almost two days later, already riding my motorcycle at hiway speed, headed for home, alongside my brother on his bike with his Gf. So that is about two days of my life that I have zero recollection of what I did. I could not even recall any concert.
To this day I have no knowledge of what I did during those missing hours. My brother wouldn't say, and I can't ask him anymore on account of he is dead.
What I really want to know is who or more likely, what, in the heck was in charge of my mind and body during that time.
In any case, after that I always counted my beers by putting the caps in my pocket, and never got past pleasantly buzzed again. Twenty years later, I quit altogether.

Now I ask you;
What if the fella in the video, is similarly afflicted?
